The Enviolo SP hub is a continuously variable gear hub known for its smooth and intuitive shifting experience. With the SP (Sportive) version, Enviolo targets sporty bikes, including e-bikes, where a wide gear range and high load capacity are required. The system uses the Continuously Variable Planetary (CVP) transmission, which allows for seamless, stepless shifting, even under heavy loads or while stationary.

 The hub is fully enclosed, low-maintenance, and suitable for use with powerful motor systems such as those found in modern e-bikes. Shifting is manual via a twist grip (or, if available, automatic on automatic models), and the gear range is typically 310% to 380% depending on the specific model. The Enviolo SP hub is designed to handle high torque and is less susceptible to wear due to its enclosed design.

 Features summarized:
 - Infinitely variable shifting: no gear steps, always the right gear[
 - High switching range (typically 310-380%)
 - Low maintenance due to closed system
 - Suitable for powerful engines, sporty and intensive use
 - Suitable for disc brakes (brake type and mounting depending on model version)
 - Weight around 2.45 kg (depending on type and specification)
 - Modular axle for easy integration into different bicycles

 The SP hub stands out within the Enviolo range as a robust and versatile stepless gear, ideal for sporty city bikes and e-bikes.
